Patent FR-2480029-A1 (FR)
Inventor: NADLER PETER
IPC: H01H33/16
Filed: 1981-03-03
Abstract: A series circuit consisting of an auxiliary switching point having a switching-on resistor is connected in parallel with a main switching point. Both switching points are coupled via in each case one lever drive (20, 21) to a common drive rod (19) which can move between a switched-on position and a switched-off position. The lever drive (21) which is allocated to the auxiliary switching point has an angled lever (32) which is supported on a fixed-position pivoting journal (33). In order to be certain, at a low technical cost, that the auxiliary switching point switches on before the main switching point during the switching-on movement but switches off again at the end of the switching-on movement, that arm (37) of the angled lever (32) which leads to the drive rod (19) is constructed as one element of a toggle lever (37, 39) which is articulated by means of its other element (39) on the drive rod (19), can be pressed over and extends at the latest on reaching the switched-on and switched-off positions. Means (42, 43) are provided in order to bend the toggle joint (38) of the toggle lever (37, 39) in the direction of the drive rod (19) in the switched-on and switched-off positions.

Title: Fibre coated polyester tape - for insulating multicore telecommunication cables to provide flexibility for burial by ploughing in
Inventor: ORMILI BERNARD
IPC: H01B13/32
Filed: 1981-03-12
Abstract: Cables with a multiple conductor core overwrapped in turn with an impregnated insulation tape and a metallic tape are made using an insulation layer of thin polyester tape covered or coated on both faces with a cellulosic matl. The insulation layer is impregnated with a liquefied hydrocarbon either before or after the tape is wrapped about the core. The insulated core is passed through at least one calibration die prior to receiving the metallic sheath. Esp. for relatively large sizes of telecommunication cables carrying several pairs of core conductors. The polyester based insulation layer has a higher extensibility than the 3-5% characteristic of conventional paper strip based insulation which tends to break if the cable is flexed during installation - esp. laid across country by 'ploughing in'.

Title: Molecular adhesion plane substrate holder - takes any sized substrate held on plate by copolymer elastomer and resin layer pressed in place and removed by fluid pressure
Inventor: TROTEL JACQUES
IPC: H01L21/687
Filed: 1981-03-13
Abstract: The substrate holder (1) is for holding any sized plane substrate on a carrier for e.g. particle beam lithography. The substrate carrier is first prepd. with a surface layer of an elastomer mixed with a tacky substance and conducting material. Such a mixt. may be a polyisoprene polystyrene copolymer and a natural terpene resin. The carrier is prepd. by drilling holes from the plane face and placing it in a holder contg. the mixt. at a temp. above its m.pt. in the horizontal plane until the mixt. flows into the carrier. The mixt. is cooled to normal temp. and a number of the holes are cleaned off the mixt. The holes are blocked off to prevent fluid entry and the substrate placed on the holder. The substrate is pressed onto the holder by reducing the pressure under the holder, the substrate being held in place by molecular attraction. The substrate is removed from the carrier by pumping fluid under pressure through the holes in the holder. The holes are set in a matrix in the centre of the holder and surrounded by an annular groove of dovetail profile.

Title: Oak cask for ageing and maturing wine, whisky etc. - contains pocketed oak contacting element to speed process and extend life of cask
Inventor: STEM RICHARD K
IPC: C12G3/07
Filed: 1981-10-09
Abstract: A container for a liq. which is intended for drinking, partic. a cask in which wine, whisky etc. is held for a period of a ageing and maturing. The process which takes place during this period relies upon chemical reaction, over a number of years, between the liq. and the contacted surface of wood which forms the cask and/or is contained within the cask. The wood is usually oak, which may be carbonised. The container takes the form of a wooden, partic. oak, cask or barrel inside which is fitted a renewable contacting element made of wood, pref. oak. The element is designed to present max. surface area for the space which it takes up. To this end the element is pocketed with open chambers e.g. in the form of a honeycomb or egg-box. The cask is used for the storage of wines, whiskies etc. during a period of ageing and maturing. The duration of this maturing period is reduced by insertion of the contacting element.
Patent FR-2492076-A1 (FR)
Inventor: FUSSL ERWIN
IPC: C04B2/12
Filed: 1981-10-12
Abstract: For heating the shaft (1) the feed pipes (4) are combined in part-lines (14) and the latter are combined in feed lines (16), which are charged during the burning period with a solid fuel, for example pulverised coal, and a propellent gas. To maintain the fuel feed constant in time during the combustion process, the pulverised coal is weighed from a silo (27) into a metering vessel (23) and then discharged through metering locks (25) to the feed lines (16), from where it is fed by the propellent gas, for example compressed air, to the fuel lances (3), whose distribution in the shaft cross-section achieves a uniform distribution of the solid fuel and hence a burnt material whose quality is comparable with that of a material burnt with gaseous or liquid hydrocarbons.

Disclosed (I) are the organic fraction of domestic refuse, sewage sludge, lignocellulosic agricultural waste, black peat, river or bog silt, and spent mushroom compost. Addn. of (I) improves the stability of fermentation, increases gas prodn., and improves the agricultural quality of the fermented residue.

Title: Case, in particular for the packaging of video cassettes
IPC: G11B23/023
Filed: 1982-08-18
Abstract: The invention concerns a case, in particular for the packaging of video cassettes or of any other types of recording on magnetic tapes. The invention is characterised in that the jacket 6 is constituted from a plastic transparent film, printed on the inside (from the surface 61 facing the case), this film being made from a material which is miscible with that of the case in order to allow "welded" fixing on the periphery 8 of the outside face of the two parts 1, 2 constituting the said case, the printed area 7 of the film 6 being located such that it is set back from the outer edge of the said film 6 in order to leave a clear margin 63 around the edge of the latter thus favouring the joining-together of the case and the jacket. This case is applicable to any recording whose authenticity is required to be guaranteed.
